The cap replacing process is divided into 4 steps, including upper electrode cap replacing, upper electrode cap installing, lower electrode cap replacing and lower electrode cap installing, wherein, the upper electrode cap replacing, lower electrode cap installing and cap replacing processes are the same, the following takes the upper electrode cap replacing and upper electrode cap installing as an example, and introduces the working principle of the invention as follows:
the upper electrode cap replacing process:
the upper electrode is uncapped: the outer upper cover 12, the outer lower cover 13 and the stop block 14 limit the movement of the inner upper cover 25 and the inner lower cover 26, the cylinder 27 and the turntable 23 are all at initial positions when the cap removing operation is started, namely, the cylinder push rod retracts to the limit position, when the control device gives a cap replacing signal, the control device controls the welding gun to drive the electrode cap to be replaced to move to the upper part of the cap removing unit 11 and controls the electrode cap to enter the first through hole through the second through hole, the sensor detects the information that the electrode cap enters the first through hole and transmits the detected information to the control device, the control device controls the cylinder 27 to drive the cylinder push rod to do extension movement and drives the turntable base to rotate through the connector 21 and the connecting block 22 to drive the turntable force arm 28, the turntable base also drives the electrode cap clamping jaw 24 to rotate, and because the electrode cap clamping jaw 24 is provided with the rotating pin shaft 3, and two ends of the rotating pin shaft 3 respectively extend to the inner upper, In the guide sliding groove on the inner lower cover 26, the guide sliding groove guides the movement of the rotating pin shaft 3 and also indirectly guides the movement of the electrode cap clamping jaws 24, so that the plurality of electrode cap clamping jaws 24 gradually draw close to the first through hole, when the rotating disc seat rotates for 20 degrees, the plurality of electrode cap clamping jaws 24 clamp an electrode cap to be disassembled, at the moment, the rotating disc seat continues to rotate and starts to unscrew the electrode cap, namely the electrode cap clamping jaws 24 clamp the electrode cap and then rotate for 40 degrees, and because the electrode rod of the welding gun is fixed, the electrode cap and the electrode rod generate relative displacement, and the electrode cap is disassembled from the electrode rod; at this time, the sensor detects that the electrode cap is detached and transmits the detached information to the control device, the control device controls the cylinder push rod of the cylinder 27 to do retraction movement to complete detachment of the electrode cap, but the electrode cap is also possibly arranged on the electrode rod because of damping, and the control device controls detachment three to four times according to the detected information of the sensor to ensure that the electrode cap falls off.
It should be noted that when the turntable base rotates 20 °, the plurality of electrode cap clamping jaws 24 clamp the electrode cap to be disassembled, and the electrode cap clamping jaws 24 clamp the electrode cap and rotate 40 ° again, which is a process of unscrewing the electrode cap from the electrode rod, but when the electrode cap is not yet detached from the electrode rod, at this time, the turntable base drives the plurality of electrode cap clamping jaws 24 to rotate 20 ° again from the position of 60 °, because the electrode cap and the electrode rod are in taper fit, once the electrode cap and the electrode rod are relatively displaced, the electrode cap moves away from the direction of the electrode rod, and when no external force drives the electrode cap to move towards the direction of the electrode rod, only the rotary electrode cap cannot be screwed onto the electrode rod again, and therefore, in the repeated rotation of 20 ° to 60 ° when the electrode cap clamping jaws 24 clamp the electrode cap, the electrode cap can be gradually unscrewed and finally disassembled.
And (3) upper electrode capping process: after the upper electrode cap is detached, the sensor detects that the electrode cap is detached, the welding gun moves to the position right above the upper electrode cap taking position of the electrode cap storage device 2 to enable the circle center of the upper electrode rod to be concentric with the upper electrode cap, then the control device controls the welding gun to move slowly to enable the electrode rod to be slowly matched with the electrode cap and to be compressed, then the welding gun moves to the position right above to take out the mounted electrode cap, and due to the action of the spring, a vacant position after the electrode cap is taken out pushes out the next electrode cap, and due to the position limitation of the lock tongue 33, the electrode cap waits to the mounting position.
In the description of the present application, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience in describing the present application and simplifying the description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present application.
